4. Service points Lead-free solder

This product uses lead-free solder (unleaded) to help protect the environment. Please read these instructions before attempting any soldering work. Caution: Always wear safety glasses to prevent fumes or molten solder from getting into

the eyes. Lead-free solder can splatter at high temperatures (600). Lead-free solder indicator

Printed circuit boards using lead-free solder are engraved with an "F." Properties of lead-free solder

The melting point of lead-free solder is 40-50 higher than leaded solder. Servicing solder

Solder with an alloy composition of Sn-3.0Ag-0.5Cu or Sn-0.7Cu is recommended. Although servicing with leaded solder is possible, there are a few precautions that have to be taken. (Not taking these precautions may cause the solder to not harden properly, and lead to consequent malfunctions.) Precautions when using leaded solder Remove all lead-free solder from soldered joints when replacing components. If leaded solder should be added to existing lead free joints, mix in the leaded solder thoroughly after the

lead-free solder has been completely melted (do not apply the soldering iron without solder). Servicing soldering iron

A soldering iron with a temperature setting capability (temperature control function) is recommended. The melting point of lead-free solder is higher than leaded solder. Use a soldering iron that maintains a high stable temperature (large heat capacity), and that allows temperature adjustment according to the part being serviced, to avoid poor servicing performance. Recommended soldering iron: Soldering iron with temperature control function (temperature range: 320-450)

Recommended temperature range per part: Part Soldering iron temperature Mounting (chips) on mounted PCB 320±30

Mounting (chips) on empty PCB 380±30

5. Service Adjustments

Service Mode

This model has a limited service mode; there is no access to I2C parameters of any kind. The only service adjustments that can

be performed are the color temperature defaults.

Please note that to perform these adjustments, a colorimetry meter, such as a Minolta CA-100 or CA-200 is required to meas-

ure the actual screen during adjustments.

Color Temperature

This model has four (4) different color temperature defaults. The associated color temperature X:Y readings are shown below

on Table 1.

Preliminary:

Input 100 IRE white image. Allow 15 minutes warm up.

Procedure:

COLOR MODE X READING Y READING

COOL 0.268 +/- 0.01 0.283 +/- 0.01

NATURAL 0.285 +/- 0.01 0.293 +/- 0.01

WARM 0.314 +/- 0.01 0.327 +/- 0.01

Notes:

1. There are three (3) possible displays on this step, depending on

which Picture Mode is selected. Color Temperature follows Pic-ture Mode, i.e. Dynamic > Cool, Natural > Warm, Cinema >

Warm. OSD controls for Brightness, Contrast, and Color only

appear when in Natural picture mode.
